Nippon Paper’s SHIELDPLUS barrier paper has become one of the group’s key specialty packaging lines, addressing food brands that want to reduce plastic while still protecting aroma-sensitive or greasy products. The multilayer paper structure integrates a water-based coating to block oxygen and water vapor, so pouches and wraps can replace part of the plastic film traditionally used in flexible packaging. Nippon Paper describes SHIELDPLUS as offering high barrier performance against oxygen, water vapor and aroma, while still being based mainly on paper fiber.

How SHIELDPLUS is built and where it is used

At its core, SHIELDPLUS is a paper substrate coated with a thin, proprietary barrier layer that is applied in a water-based process onto the paper surface. According to Nippon Paper, this layer can be tuned for different barrier performance levels, allowing converters to choose variants optimized either for very low oxygen transmission rate (OTR) or for minimal water vapor transmission rate (WVTR), depending on the product to be packed. The high-barrier versions are positioned for dry foods such as instant coffee, tea, snacks and confectionery, while medium-barrier grades can target cereal or powdered products that are less sensitive to moisture.

Unlike conventional plastic laminates, which often combine PET, aluminum foil and polyethylene to achieve the required performance, SHIELDPLUS relies on paper as the structural base, with only a thin coating and, if needed, a minimal sealing layer. This structure supports weight reduction in plastic content compared to full-plastic pouches, while still enabling heat sealing on standard packaging lines when paired with compatible sealant films or extrusion coatings. For brand owners, this means they can redesign stand-up pouches, stick packs or flow wraps with a higher share of paper without completely changing existing filling equipment.

Nippon Paper emphasizes printability as another differentiator of SHIELDPLUS. Because the surface is paper-based, converters can apply standard flexographic or gravure inks without extra surface treatments, which helps retain sharp graphics for premium food packaging. The company also highlights that the paper substrate can be sourced from responsibly managed forests under its internal environmental policies, aligning the product with retailers’ sustainability scorecards and life cycle assessment considerations, even though final recyclability depends on local collection and sorting systems.

From a market perspective, SHIELDPLUS positions Nippon Paper in a competitive segment alongside European and North American paper groups that are also commercializing barrier papers for flexible packaging. Industry reporting on fiber-based packaging notes that food brands are driven by both regulatory pressure on single-use plastics and by retailer pledges to increase the share of recyclable or renewable materials in private-label packaging. Barrier paper solutions such as SHIELDPLUS therefore compete not only on technical performance but also on how easily they integrate into existing converting infrastructure and whether they meet retailers’ specifications for packaging recyclability logos and claims.

The product also fits strategically with Nippon Paper’s broader shift away from commoditized printing and writing papers into growth areas like packaging materials, household paper and functional materials. In its medium-term business plan, the group explicitly calls out packaging as a pillar for earnings, with investments in coated paperboard, liquid packaging and specialty barrier technologies. For investors following this structural change, SHIELDPLUS is an example of how the company aims to capture higher-margin niches by using its coating and paper-forming expertise to meet brand owners’ packaging design briefs.
